Wyvern

The Wyvern Fountain Pen Company was established in 1896.

…and that’s just about all I’ve got, which is troubling, as they were apparently a reasonably successful British pen-maker, producing pens and pencils for a variety of markets. They closed up in the 1950s, although exactly when is also beyond me; I found a 1956 patent in the company’s name, but it was for some tool used in the setting of stones in jewelry, so pen production may have already have dried up.
